Diffs page shows "not added or updated" for Project Summary Report [4]

[BCerki]

Describe the Bug:

On the diffs page, a diff should only be shown if the user changed a form. In the project summary report section, we see "Project Summary Report not updated" if there's been no change. It's not inaccurate, but it's inconsistent.

I think the CollapsibleFormWidget may be displaying the wrong component for the Project Summary Report (the conditionality in app/components/Form/ProjectSummaryReportFormSummary.tsx looks ok)

Probability (how likely the bug is to happen, scored from 1-5): 3 (For example, probability of 5 is something like "it happens to all users every time they log in." Probability of 1 "only happens to certain users when a really specific and unlikely path is followed.")

Effect (how bad the bug is when it does happen, scored from 1-5): 1 (For example, effect of 5 is "the entire app crashes and makes it unusable for all users" or "the bug causes the wrong data to be saved, with critical information (e.g. payment) being affected." Effect of 1 is "It makes some styling look a little bit weird.")

Steps to reproduce the behaviour:

• create a general revision for an IA project
• navigate to the summary page
• see a message under the project summary header
